Abstract
In general, a pedestrian crossing is a place marked by a road sign or road marking provided for pedestrians crossing in accordance with the Road Traffic Act. However, it is often the case that vehicle drivers may not be able to find a pedestrian crossing at night when they are driving at night. In this dangerous situation, the present invention generates a beam that distinguishes pedestrian crossings and pedestrians, It allows pedestrians to cross the pedestrian crossing and pass the beam so that pedestrians can only pass on the pedestrian crossing. When the pedestrian crosses the crosswalk, .
Description
BACKGROUND OF THE
[0002] Generally, a crosswalk is a place marked with a road sign according to the Road Traffic Act or a person designated for crossing a pedestrian by road marking. However, it is often the case that vehicle drivers can not find the pedestrian crossing at night when they are driving at night.
Currently, there are 5.28 pedestrian traffic accidents per 100,000 population in our country, which is much higher than the OECD average of 1.58. Therefore, it is necessary to prevent pedestrians from dying through these traffic accidents.
In the prior art, a "crosswalk pedestrian protection device" disclosed in Japanese Laid-Open Patent Publication No. 2003-979440000 discloses a system in which a green laser beam belt is formed on a vehicle stop line of a pedestrian crossing so that a driver can easily identify at night, Which is similar to the present invention in that it can ignite the driver on the crosswalk and can not proceed, but it can distinguish the driver's vehicle speed, ignoring the walking signal, The fact that a beam belt is formed to prevent a pedestrian from endlessly crossing is different from the technical content of the present invention.
In addition, in the prior art, there is a " safety device for pedestrian crossing "disclosed in Korean Patent Publication No. 2000-0001929, but when a pedestrian crosses the safety line of the pedestrian crossing, It is similar to the present invention in that a danger warning is sounded so that the pedestrian returns to the safety boat of the crosswalk while emitting an alarm sound. However, when the pedestrian passes the red laser beam at the boundary laser beam of the roadway and the sidewalk, Which is different from the technique of the present invention in that an alarm sound is emitted when a green laser beam that crosses the crosswalk and the roadway in green signal passes.
[0003] Generally, a large portion of traffic accidents occur on a pedestrian crossing, which includes night crosswalks, crosswalks in dark, empty and open areas, pedestrian crosswalks in the event of rain or snow, And the difficulty in easily identifying pedestrians passing through a pedestrian crossing on a road where communication of the vehicle frequently occurs.
In addition, it is a habit to rush when it changes to a speeding driver and a speeding driver ignoring a pedestrian signal or a traffic signal, and a pedestrian passing by the road without passing over a pedestrian crossing in order to prevent the accident more.
[0004] In the above-mentioned "problem to be solved", it is difficult to recognize that a driver is walking a pedestrian crossing at night, and a method of overcoming the habit of crossing a pedestrian crossing pedestrian crossing and pedestrian crossing Respectively.
First, a laser beam is formed using a blue LED beam that clearly distinguishes between a roadway and a pedestrian crossing so that a driver can recognize the position of the pedestrian crossing and pedestrians from afar at night, and pedestrians can cross the pedestrian crossing In order to clarify the roadway and the sidewalk in the red signal, a colorless LED is formed so that the pedestrian who is crossing the pedestrian can detect the sensor To pass the green signal.
[0005] When a pedestrian crosses a pedestrian crossing even when the pedestrian traffic light is operating at night in a pedestrian crossing, a pedestrian crossing at night, in which the vehicle passes through the pedestrian crossing and ignores the pedestrian signal, , The non-EH may not pass the pedestrian passing through the road where the visibility of the snow is not secured, the congestion of the vehicle and the traffic of the vehicle frequently, .
If the pedestrian signal is changed from a green signal to a red signal in the above situation, it is still impossible to avoid traffic accidents if the pedestrian is still running late (in fact, human accidents occurring in such situations take a large part.
The present invention generates a beam that distinguishes crosswalks and roadways added from existing technologies in the above-mentioned dangerous situation so that the pedestrian can safely cross the pedestrian crossing, and when the pedestrian passes the beam so that the pedestrian can pass only on the pedestrian crossing, To allow pedestrians to cross a pedestrian crossing so that they can pass only in a safe area, thereby preventing a safety accident in advance.
It also generates a transparent led beam between the pedestrian crossing and the sidewalk so pedestrians can keep the pedestrian crossing and the safety distance when the pedestrian is crossing or red, allowing the pedestrian to wait for the signal in the safe area even when waiting for the signal.
